The VForce reed valve system by Moto Tassinari has been the reed valve system of choice by anyone serious about two-stroke engine performance for the last 25+ years. The simple premise of the VForce reed valve system is to increase engine power and throttle response by increasing the efficiency over a conventional reed valve design by doubling the reed-tip surface.
The V-Force 4X has a newly designed reed valve that achieves the same extended reed petal life of the V-Force 4R. This is achieved through an all-new reed cage surface design and reed petal combination that increases reed petal life.
For select Yamaha YZ250 and YZ250X motorcycles this has been designed to offer you exceptional durability and overcome the shortcomings of the stock reed valve system.
